The content of the invention
For above-mentioned existing issue, this practicality provide it is a kind of it is new it is anti-beat the high-power contact of arc composite construction, surely
Qualitative good, guide surface is more, and contact area is big, and contact resistance is small, and generation heat is small, and current capacity is high, can be applied to hundreds of amperes
In the connector of high current, transmission stability is improved, and reduces the power being lost on electric connector.
The technical solution adopted by the present invention is：One kind is anti-to beat the high-power contact of arc composite construction, including jack and contact pin,
It is characterized in that：The jack includes receptacle body, center contact pin, jack hat spring, the anti-contact of jack, and the contact pin includes contact pin
The anti-contact of body, contact pin, contact pin hat spring, the receptacle body front end plugs together jack built in cavity wall inside groove and is preced with spring, plugs together intracavitary and set one
Front end is equipped with the center contact pin of anti-contact, and the pin body front end is equipped with anti-contact, and pin body front end is plugged together in receptacle body front end
It plugs together in intracavitary jack hat spring, pin body front end plugs together intracavitary and is equipped with the contact pin hat spring plugged together with center contact pin.
The center contact pin rear end, which is connected through a screw thread, to be placed in receptacle body, the end of thread circumferentially have symmetrical plane it is convenient with
Center contact pin is screwed into position by frock cooperation.
Two anti-contact outer ends are chamfering cylindrical surface, and inner end is axially packed into center contact pin front end internal bore groove or contact pin for reversed acanthoid
In the internal bore groove of body front end.
End section is semicircle after the receptacle body, radially there is multiple threaded holes.
The pin body rear end is equipped with annular groove and section crimps cable tubular to be packed into.
Two hat springs are discontinuous, the not closed circular being made of both ends fixed part and middle interconnecting piece, and connecting portion is by even
The uniform alternate composition of continuous concave-convex shrapnel.
Pin body, center contact pin, receptacle body material are red copper, and two hat springs are beryllium-bronze, and surface treatment is silver-plated, and two is anti-
Contact uses PEI plastics.
After receptacle body of the present invention and pin body plug together, jack is preced with spring and provides normal pressure to pin body surface, make receptacle body and
Electrical contact is formed between pin body, the normal pressure of increasing is provided, center contact pin generates electrical contact with contact pin hat spring.Overall structure is steady
Qualitative good, contact area is big, and contact resistance is small, and generation heat is small, and current capacity is high, can be applied to the company of hundreds of amperes of high currents
It connects in device, improves the stability of transmission, and reduce the power being lost on electric connector, connector is easy to use, safe.
